WS-C4224V-8FXS: Catalyst 4224 Voice Gateway Switch for Data, Voice, and Video

Document ID: 17954

Updated: Mar 30, 2005




The Cisco Catalyst 4224 Access Gateway switch extends data, voice, and video to the small branch office that deploys IP Telephony in an unprecedented fashion. With the delivery of IP routing, Ethernet switching, and voice gateway capabilities into a two-rack unit (2U) chassis, the deployment of converged IP communications has never been easier or more cost effective. For more information about the Catalyst 4224 Access Gateway switch, refer to these documents:

The Catalyst 4224 has twenty-four 10/100 switched Ethernet ports with integrated inline power, and advanced Quality of Service (QoS) features. This makes it an ideal choice to extend Cisco IP Telephony-based Voice over IP (VoIP) networks to small branch offices of up to twenty-four users.

The Catalyst 4224 includes an integrated eight-port Foreign Exchange Station (FXS) module to support devices such as analog phones, fax machines, and modems. The Catalyst 4224 shares a modular Voice Interface Card (VIC), and WAN Interface Card (WIC) with the Cisco 1600, 1700, 2600, and 3600 series platforms. This protects customer investment, streamlines operation costs associated with sparing of parts, and simplifies training.

A high-performance MPC 8260 processor provides all the processing power required to deliver voice, streaming video, and data to the branch office.

Ordering Information

  • Product Number: WS-C4224V-8FXS

  • Description: Catalyst 4224 Voice Gateway switch


  • 24 10BaseT/100BaseTX autosensing ports, each delivers up to 200 Mbps of bandwidth (full duplex) to individual users, servers, or workgroups to support bandwidth-intensive applications.

  • Forwarding and filtering at full wire speed on each port.

  • Support for up to 8000 unicast and 256 multicast addresses.

  • Protocol Independent Multicast (PIM), and Internet Group Management Protocol (IGMP) snooping.

  • Four queues on each 10/100 port, enabling network traffic prioritization and seamless data, voice, and video integration through the Institute of Electrical and Electronic Engineers (IEEE) 802.1p protocol.

  • Port-based reclassification that allows users to reclassify IEEE 802.1p Class of Service (CoS) values on a per-port basis for a finer granularity of QoS control.

  • Per-port broadcast, multicast, and unicast storm control that prevents faulty end stations from degrading overall system performance.

  • Inline 48-volt DC power to all 24 10BaseT/100BaseTX autosensing ports.
